I also just switched over from a storm town Eris and have to say that I am quite impressed. There might be the slightest lag but it is really not all that noticeable. The interesting thing is that I honestly was happy with my storm as of yesterday, but had the opportunity to get one for free, so I bit the bullet with partial intentions to sell it.

Honestly this device does everything well, the keyboard is amazingly accurate and quite pleasant to use.
